This activity, created by Arthur N. DiVito, Ph.D, simulates mixture problems by using red and white colored beads. Mixture A is 70% red, and mixture B is 40% red (as determined by weight).
Students will be presented with two different gas stations, and will have to come up with equations to determine the price of gas at each.
Students will calculate relationships in the solar system using scientific notation. This requires that students understand how to multiply and divide exponential expressions.
Using systems of equations, students will determine the missing components in the ratios used to determine batting average.
he main purpose of this lab is to explore the proportionality of forearm length and height. The students will record their heights and forearm lengths, first plotting on a table.
In this activity students will explore levels of Carbon Dioxide (CO2) in the atmosphere over time.
Students create ordered pairs, graph depreciating car values, and calculate rates of depreciation, then identify that the rate of depreciation = slope of the line.

In science, students often start their graphs at an origin other than \((0, 0)\). Also the scales are often very large or very small and variables, other than \(x\) and \(y\), are used.

This investigation of the genetics of the Sickle Cell trait via a mathematical model uses probability and teaches properties of quadratic functions and the concept of optimization of a function.
The functions that model the process of the elimination of alcohol from the body serve as an introduction to a study of rational functions at an intermediate algebra level.
